RAZÕES PARA A RÁPIDA EVOLUÇÃO DO CROMOSSOMO Y

O cromossomo Y está presente em apenas uma cópia nos machos, tornando-o mais suscetível a mudanças.

Alta taxa de mutação devido à extensa replicação de DNA durante a produção de esperma.

Enquanto isso, o cromossomo X...

É altamente conservado entre as espécies de primatas.

É altamente conservado entre as espécies de primatas.

Isso indica seu papel crucial na reprodução.

Preservação do Material Genético

O cromossomo Y contém material genético altamente repetitivo, como repetições palindrômicas. Esse material pode proteger genes vitais de erros de replicação.
